Not sure if this has been handled before or not, but I'm losing my mind here.
I'm using a couple of custom image sizes for thumbnails on my page. Since the 3.5 update I've encountered a problem with at least one of them so far.
When I upload an image and set it as featured image and don't edit the thumbnail all works fine. However, if I use the WordPress media editor to change the way the thumbnail looks, one of my custom image sizes stops working.
What previously happened was that WordPress added '-60x40' to the image link. It still does this when I don't crop or edit the thumbnail, but when I do, it just uses the original link (so without '-60x40'), resulting in it showing the full image. This breaks my custom image size, because when I use an image of, let's say, 500x500 pixels, it will show it on my page as 40x40 pixels.
Has anyone noticed this same problem or does anyone know a solution to this?
Thank you very much!
